Answer:
C = $137.50
Step-by-step explanation:
Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.
Now, let's make an equation:
C = 50 + 25(3.5)
Now, multiply 25 and 3.5 together:
C = 50 + 87.5
Now we just combine the like terms:
C = $137.5
Hope this helps :)
Regardless of the sign of
, we have
(never negative). But multiplying by -1 makes it negative.
On the other hand,
which can never be negative for real

Answer: length of DE is about 3.3 ft
Step-by-step explanation: A calculator is necessary!
DE is the unknown hypotenuse of the triangle
get the sine of 23° = 0.3907311285
Use the equation for sine
<em>sin = o/h</em> .
To find h, Substitute values for sin and o. O is EC, Opposite the 23° angle D
<em>0.3907311285 = 1.3/h</em> multiply both sides by h
h(0.3907311285) = 1.3 divide both sides by 0.3907311285
h = 1.3/0.3907311285
3.327096065 = h, the length of the hypotenuse, DE.
Answer:
Answer:
3x + 3y = 0
7x - y = 8
Step-by-step explanation:
Answer- KG⎯∥JH⎯
the given figure is a trapezium in which CF||DE
Reflection of figure CDEF and shifting it by 3 units does not change the shape of the figure but changes only its position in the x-y plane.
so, the shape of the figure GHJK will be same as that of CDEF.
so sides, KG⎯∥JH⎯
